SEOUL, Dec 30 (Reuters) - South Korea's acting President

Choi Sang-mok on Monday ordered an emergency safety inspection

of the country's entire airline operation system once the

recovery work on the Jeju Air crash is finished.

South Korea's deadliest air accident ever killed 179 people

on Sunday, when an airliner belly-landed and skidded off the end

of the runway, erupting in a fireball as it slammed into a wall

at Muan International Airport.
